Isro successfully tests cryogenic engine for upcoming LVM3-M6 mission

ISRO on Saturday said it has successfully conducted the flight acceptance hot testing of the cryogenic engine identified for the sixth operational mission of LVM3 launch vehicle (LVM-M6) at ISRO Propulsion Complex, Mahendragiri in Tamil Nadu. The LVM3 (Launch Vehicle Mark-3) is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). The cryogenic engine of every mission undergoes hot testing as part of its acceptance process for the flight, ISRO said in a statement. Hot tests for the indigenous cryogenic engine (CE20) used in the Cryogenic Upper Stage of LVM3 were so far performed at the High-Altitude Test (HAT) facility at ISRO Propulsion Complex (IPRC) where vacuum conditions are simulated with complex installations, limiting the maximum hot test duration to 25 seconds. "In the current test, the engine was tested for a longer duration of 100 seconds for the first time using an innovative Nozzle Protection System under non-vacuum ...

Isro's POEM-4 successfully completes one thousand orbits on March 4

ISRO on Friday announced that the fourth edition of the PSLV Orbital platform Experiment Module (POEM-4), the repurposed spent upper stage of the PSLV vehicle used for the space docking experiment mission, has successfully completed 1,000 orbits on March 4. The PSLV-C60 Mission was launched on December 30, 2024, and POEM-4 began its operations subsequent to the successful injection of the SPADEX spacecraft, it stated. In a statement, ISRO said, "POEM-4 was configured as a three-axis stabilised platform that carried 24 payloads including 10 payloads from Non-Governmental Entities (NGEs) and 14 payloads from ISRO. All the payloads including those from NGEs have completed the intended experiments in orbit." According to ISRO, POEM-4 carried out experiments in space robotics, germination of seeds and growth of bacterium in microgravity, green propulsion, laser ignition of pyro thrusters, amateur radio transmission and advanced sensors. A space start-up also tested the uplinking and ...

We don't outsource our critical software system : Ex-Isro chief Somanath

Software development at ISRO has always been an internal responsibility, driven by our own scientists and engineers across domains from environmental science to physics, computer scienceand more, the space agency's former chief S Somanath said. "We don't outsource these critical software systems because the deep integration between science, technology, and applications requires intimate domain understanding" he said at Software Product Management (SPM) Summit held by IIMB. The two day summit was held on February 28 and March 1, celebrating its 7th edition around the theme 'Software Product Management Excellence at Scale'. Somanath elucidated the evolution of software product management and development for space programs, emphasising the shift from environmentally focused missions to commercially operated systems. "Every piece of software, whether for satellite operations, data analysis, or mission simulations, is built in-house to ensure accuracy, security, and scientific rigor. Ov

NISAR space plan with US example of India's cost-effectiveness: Somanath

Former ISRO chairman S Somanath has highlighted the cost-effectiveness of India's space programmes and noted that for the same satellite and share of work, the country will incur five-time less expenditure compared to the US for an upcoming mission. He was referring to the NASA-ISRO Synthetic Aperture Radar (NISAR) mission. The joint National Aeronautics and Space Administration (NASA)-Indian Space Research Organisation (ISRO) project will map the entire globe and provide data for understanding changes in Earth's ecosystems, ice mass, vegetation biomass, sea level rise, ground water and natural hazards. Somanath on Wednesday stressed on greater private sector role to push India's contribution in the global space economy from current 2 per cent to 10 per cent. Taking about NISAR, a joint Earth-observing radar mission, he said one part of the payload is being developed by the US, and the other by India. The former ISRO chief was speaking at an interactive session on the topic, "Indi

India, US call for space collaboration, launch new innovation bridge

Calling for ramping up collaboration in space exploration, including on long-duration human spaceflight missions, Prime Minister Narendra Modi and President Donald Trump hailed 2025 as a pioneering year for US-India civil space cooperation. The two leaders, who also launched INDUS Innovation bridge, held wide-ranging talks on Thursday (Friday IST) focussing on broadening the bilateral partnership, including in the fields of defence, energy, space and critical technology. Modi and Trump called for more collaboration in space exploration, including on long-duration human spaceflight missions, spaceflight safety and sharing of expertise and professional exchanges in emerging areas, including planetary protection, according to a joint statement issued after the discussions. The leaders committed to further commercial space collaboration through industry engagements in conventional and emerging areas, such as connectivity, advanced spaceflight, satellite and space launch systems, space .

Isro develops 10-tonne 'Vertical Planetary Mixer' for solid motors

ISRO on Friday said it has developed and realised the ten-tonne propellant mixer for solid motors. Solid propulsion plays a crucial role in Indian Space Transportation Systems and vertical mixer is one of the critical equipment in solid motor production, ISRO said in a statement. "Solid propellants are the backbone of rocket motors, and their production requires precise mixing of highly sensitive and hazardous ingredients," the statement read. The space agency said that towards increasing the production scale of solid motor segments, Satish Dhawan Space Centre in Sriharikota in collaboration with Central Manufacturing Technology Institute (CMTI), Bengaluru has successfully designed and developed 10-tonne Vertical Planetary Mixers for processing the solid propellants. ISRO has termed it a significant technological marvel. It added that the 10-tonne vertical mixer is the world's largest solid propellant mixing equipment. The development involves collaboration with academia and ...

Isro successfully carries out vacuum ignition trial of cryogenic engine

ISRO on Saturday said that it has successfully carried out the ignition trial of the indigenous CE20 cryogenic engine powering the upper stage of LVM3, with a Multi-element igniter under vacuum conditions, which simulates the engine ignition in the vacuum condition of space. This test was carried out on Friday in the High Altitude Test Facility at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu, ISRO said in a statement. This engine is crucial for the Gaganyaan mission, India's ambitious crewed space mission. During this test, the ignition of the engine Thrust Chamber was carried out with a multi-element igniter in a vacuum, under the tank pressure conditions that are expected to prevail at the time of restarting the cryogenic engine in flight. The performance of the engine and the facility during the test was normal and as expected. Restarting a cryogenic engine is inherently complex and as part of the studies related to the restart operation, ISRO is exploring the initiation of

Isro's NVS-02 satellite suffers setback after thrusters fail to fire

ISRO's attempts to place the NVS-02 satellite in the desired orbit suffered a setback after the thrusters on board the spacecraft failed to fire, the space agency said on Sunday. The NVS-02 satellite, which was crucial for India's own space-based navigation system, was launched on January 29 on board the GSLV-Mk 2 rocket which was ISRO's 100th launch from the spaceport at Shriharikota. "But the orbit raising operations towards positioning the satellite to the designated orbital slot could not be carried out as the valves for admitting the oxidizer to fire the thrusters for orbit raising did not open," the space agency said in an update to the GSLV-F15 mission on its website. The satellite is orbiting the Earth in an elliptical Geosynchronous Transfer Orbit (GTO) which is not suitable for the navigation system. "The satellite systems are healthy and the satellite is currently in elliptical orbit. Alternate mission strategies for utilising the satellite for navigation in an elliptica
